I don't see the need to change then. It should remain the locale.

You misunderstand Latin 1 then. If you read the contents with Latin1 and write 
using Latin1, you get exactly what you had before. No data is lost.

That's a good behaviour, since there is no QTextCodec to change the codec.

For user applications (that is, other than qmake, moc, uic, etc.) that turned 
off QTextCodec, there's nothing that we can do. If you turn off the concept of 
codecs, then you can't change it.
